In this networking tutorial, you will learn:

 Ethernet Cable Categories

There are many Ethernet cable options available, and each one of them has its unique purpose and use. Therefore, It is important to understand each cable and its application if you want to acquire in-depth knowledge about the types of Ethernet cables. You need to choose the higher quality cable, which will be stronger, faster, and a better fit for your specific needs.

However, depending on your hardware, you can select your below-given ethernet cabling category.

Category-3

Cat3 cable is an earlier generation of cable, which supports a maximum frequency of 16 MHz. This cable may have 2, 3, or 4 copper pairs. Cat3 type of Ethernet cable is still used for two-line telephone systems and 10BASE-T networks. It is also used for alarm system installation or similar kinds of applications.

Category-5

These cables are slower compared to modern-day hardware requirements. So, you should use this type of Cable only if you have older hardware that demands outdated hardware.

Category-5e

Cat5e is one of the most popular cabling types of an ethernet cable used for deployments because of its ability to support Gigabit speeds at a cost-effective price.

Cat 5e can support up to 1000 Mbps speeds, which is flexible enough for small space installations. Therefore, it is widely used in residential areas. Cat5e is one of the least expensive cabling options available in the market.

Category-6

Cat6 cabling support up to 10 Gbps and frequencies of up to 250 MHz. These types of cables are more tightly twisted and feature two or more twists per centimeter. It only supports 37-55 meters when transmitting 10 Gbps speeds.

Category-6a:

Cat6a ethernet cable supports bandwidth frequencies of up to 500 MHz. Cat6a cabling is thicker compared to Cat6, making it less flexible. That is why it is more suited for industrial environments at a lower price point.

Category-7:

Cat7 has the ability to transmit up to 40 Gb at 50 meters and 100 Gb at 15 meters. This type of ethernet cable offers extensive shielding to decrease signal attenuation. It is relatively stiff in comparison to previous generations of cabling.

Cat7 type of Cable is suited for use in Datacenters and large enterprise networks. However, Cat7 has not been approved as a cable standard for telecommunications.

Category-8:

Category 8 cable is designed for operations of up to 2000 MHz. CAT8 cables work with 25/40GBASE-T Gigabit Ethernet; this reduces power consumption and is designed for bandwidth-intensive data center applications.

This type of Cable is ideal to use where the distances between units are short. CAT8 cables are backward compatible with previous Categories of ethernet cables.

Cat Types:

Cable Type Shielding Maximum Frequency Max Data Rate Speed
Cat 3 No 16Mhz
10Mbps
Cat 5 No 100MHz 100 Mbps 100Mbps
Cat 5e No 100MHz 1,000 Mbps / 1 Gbps 1Gbps
Cat 6 Sometimes 250Mhz 1,000 Mbps / 1 Gbps 1Gbps
Cat 6a Sometimes 500MHz 10,000 Mbps / 10 Gbps 10Gbps
Cat 7 Yes 600Mhz 40,000 Mbps/ 40 Gbps 10Gbps
Cat 8 Yes 2GHz 25 Gbps or 40 Gbps 40Gbps

Type of Cables:

Fiber-optic cabling:

Fiber-optic cable
Fiber-optic cable

Fiber optic cables mostly consist of a center glass, and different layers of protective materials surround it. Fiber-optic cabling transmits light in place of electronic signals, which removes the issue of electrical interference. This makes it an ideal selection for the environments that contain a large amount of electrical interference.

This type of network cable offers an ability to transmit signals over longer distances. It also provides the ability to carry information at faster space.

Two types of fiber-optic cables are:

  • Single-mode fiber (SMF)–This type of fiber optic cable uses only a single ray of light to carry data. Used for larger distance wiring.
  • Multi-mode fiber (MMF)–This type of fiber-optic uses multiple rays of light to carry data. Less expensive than SMF.

Four types of connectors in network that are mostly used for fiber optic cable are:

  • ST (Straight-tip Connector)
  • SC (Subscriber Connector)
  • FC (Fiber Channel)
  • LC (Lucent Connector)

Coaxial cabling:

Coaxial cable
Coaxial Cabling

Coaxial Cable is a standard for 10 Mbps Ethernet cables. These types of cables consist of an inner copper wire cover with insulation and another shielding.

It has a plastic layer that offers insulation between the draided metal shield and center conductor. Coaxial cabling has a single copper conductor in its center.

Types of Coaxial Cable are 1) RG58 2) RG8 3) RG6 4) RG59

Twisted-pair cabling:

Twisted-pair cable
Twisted-pair cable

Twisted-Pair Cabling is a type of cabling in with pairs of wires are twisted together to stop electromagnetic interference (EMI) from other wire pairs.

Two types of twisted pair cables are 1) Unshielded Twisted Pari 2) Shielded Twisted pair

Types of Shielded Ethernet Cables:

Here are some important Shielded Ethernet Cables

Cable Name Full Form Description
F/UTP Foiled/Unshielded Twisted Pair This type of Cable will have a foil shield which can be wrapped around unshielded twisted pairs. It is commonly used in fast ethernet deployments.
S/UTP Braided/Unshielded Twisted Pair (S/UTP) Cable It will cover with a braided shield around unshielded twisted pairs.
S/FTP Braided Shielding/Foiled Twisted Pair In this type of shield ethernet cable, each twisted pair is enveloped covered with foil.
SF/UTP Braided Shielding+Foil/Unshielded Twisted Pairs This cable braid has a cover around a foil wrap that encloses unshielded twisted pairs.
F/FTP Foiled/Foiled Twisted Pair This type of FTP cable encloses all copper pairs in foil.
U/FTP Unshielded/Foiled Twisted Pairs This cable only envelopes the twisted pairs in foil.
U/UTP Unshielded/Unshielded Twisted Pair. In this type of cable, no sheathing is used. Standard Cat5e is a common cable example of U/UTP cables.

1- Visual inspection: Checks for missing or any burning on resistance.   2- Using Digital Multimeter: You can check the resistor resistance by selecting the ohm range in the digital multimeter, If the resistor is in circuit, you will generally have to remove the resistor so you are testing only the resistor value and not the other components in the circuit.   Connect test probes across the two points of the resistor as shown in the photo, polarity isn’t important, value of resistance shown is 9.86 kΩ. Note: All resistors have a specific tolerance rating. The tolerance rating is marked by a color band on the end of the resistor’s body, normally the band is gold indicating 5 % tolerance. If the tolerance band is silver, then the rating is 10 %. How to test SMD Resistors: Because of the small size of SMD resistors, there is often not room for the traditional color band code to be printed on them. Therefore, new resistor SMD codes were developed. The most commonly seen codes are the three

IP Address: internet protocol

-
   What is an IP address?     An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.     It serves two main functions: identifying the host or network interface and providing the location of the device in the network. Types of IP addresses:     IPv4: This is the most common type of IP address used today. It consists of four sets of numbers separated by periods (e.g., 192.168.0.1). IPv4 allows for approximately 4.3 billion unique addresses.     IPv6: With the increasing number of connected devices, IPv6 was introduced to address the depletion of IPv4 addresses. It uses eight sets of numbers separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv6 provides a significantly larger address space. How IP addresses work:     When a device wants to communicate with another device over the internet, it needs to know the destination device's IP ad
